Description

Technical Field

[0001] The invention relates to the technical field of silver powder manufacturing, and in particular to a silver powder manufacturing device with the function of gathering powder. Background Art

[0002] In the manufacturing process of silver powder, the traditional method is to prepare silver powder by mechanically grinding and crushing bulk silver materials (such as silver bricks or silver blocks). This process usually involves using grinding rollers to apply pressure to the bulk silver materials to achieve the purpose of crushing and refining. However, in actual operation, especially in the final stage of the grinding process, when most of the silver material has been processed into powder or fine particles, the remaining corners are irregular in shape and small in size, and the traditional pressurization structure is difficult to effectively apply sufficient pressure to these residual parts. This not only leads to low grinding efficiency, but also affects the quality of the final product, failing to fully ensure that all silver materials can be evenly ground to the required particle size. In addition, improper handling of the remaining corners may also result in larger particles in the finished silver powder, thereby affecting its performance in subsequent applications. For example, in high-precision application fields such as electronic components and conductive inks, the particle size distribution of silver powder has a crucial impact on its conductivity and adhesion.

[0003] In order to solve the above problems, we propose a silver powder manufacturing device with the function of gathering powder. The silver powder manufacturing device can apply effective pressure to the remaining corners when grinding to the final stage, ensuring that even the most difficult corners can obtain good grinding effects, thereby improving the overall quality and production efficiency of the silver powder.

[0009] Preferably, a rotatably connected roller is provided at the bottom end of the pressing frame, so as to press the silver block without affecting the movement and transportation of the silver block.

[0012] The beneficial effects of the present invention are as follows: 1. The silver block is placed in the placement channel, and the push frame moves to the left to push the silver block close to the coarse grinding roller. The silver block is initially ground by the rotation of the coarse grinding roller. The silver powder after preliminary grinding is filtered out by the screen to remove larger particles. The filtered particles enter the placement box, and then the larger particles are introduced into the reflux frame by rotating the placement box, and finally transported to the coarse grinding roller for re-grinding. The silver powder ground by the coarse grinding roller falls downward and is finely ground by the fine grinding roller. The ground silver powder is gathered by the gathering bucket and falls into the collection frame to prevent the silver powder from being scattered and falling. When the push frame pushes the silver block to the final stage of grinding, the first top block will contact the right side of the last corner of the silver block, thereby pushing the edge of the silver block to the left, applying sufficient pressure to the irregularly shaped small pieces of silver block so that the silver block edge can fit with the coarse grinding roller for effective grinding. When the push frame pushes the silver block to the left for grinding, the piston rod slides downward to drive the pressing frame to move downward to press the ground end, ensuring that the silver block moves stably to the left and preventing the silver block from shaking and tilting to affect the grinding. In this way, the silver block can be fully ground.

[0013] 2. When the collection frame is pulled out from the rack, the limit block will slide to the left on the collection frame under the action of the magnet adsorbing the rack, and then the folding film will be unfolded to cover the upper side of the collection frame to prevent silver powder from flying.

[0014] 3. The output shaft of the driving motor rotates to drive the friction frame to rotate and squeeze the second top block, thereby driving the screen to vibrate and improve the filtering effect of the silver powder, so as to prevent the silver powder from clogging and accumulating on the screen.

The protective shell 11 is fixedly connected to the upper left part of the frame 1, the driving motor 12 is fixedly connected to the upper side of the frame 1, the coarse grinding roller 13 is fixedly connected to the upper part of the output shaft of the driving motor 12, the coarse grinding roller 13 is located in the upper part of the frame 1, the fine grinding roller 14 is fixedly connected to the lower part of the output shaft of the driving motor 12, the fine grinding roller 14 is located in the middle part of the frame 1, the gathering bucket 15 is fixedly connected to the lower part of the frame 1, the gathering bucket 15 is located below the fine grinding roller 14, the collection frame 16 is slidably connected to the bottom of the frame 1, and the upper right part of the frame 1 slides A push frame 17 is dynamically connected, and a placement channel for conveying the silver block 1701 to the coarse grinding roller 13 is provided on the upper right part of the frame 1. Two electric slide rails 18 are fixedly connected on both sides of the front and rear of the upper right part of the frame 1. The push frame 17 is slidably connected to the electric slide rails 18. Two connecting frames 19 symmetrical front and back are fixedly connected to the left part of the push frame 17. An elastic rope 110 is connected to the upper part of the connecting frame 19. Two first top blocks 111 symmetrical front and back are rotatably connected to the left part of the placement channel of the frame 1. The tail end of the elastic rope 110 is connected to the upper part of the first top block 111. A torsion spring 112 is connected between the first top block 111 and the frame 1. A recovery component for conveying unground metal particles back to the top of the coarse grinding roller 13 for regrinding is provided on the frame 1.

[0032] In the initial state, the left end of the elastic rope 110 is rolled up on the upper part of the first top block 111. When using the device, the staff drives the push frame 17 to slide to the right through the electric slide rail 18, and the push frame 17 slides to the right to drive the connecting frame 19 to move to the right. The connecting frame 19 moves to the right and pulls the first top block 111 on the front side to rotate clockwise through the elastic rope 110, and the first top block 111 on the rear side rotates counterclockwise, and the torsion spring 112 is deformed. After the first top block 111 rotates, the elastic rope 110 is stretched again, and then the staff puts the silver block 17 01 is placed in the placement channel. At this time, the silver block 1701 is located between the front and rear first top blocks 111. Then the staff operates the drive motor 12, and the drive motor 12 drives the coarse grinding roller 13 and the fine grinding roller 14 to rotate. At this time, the staff drives the push frame 17 to move to the left through the electric slide rail 18. The push frame 17 moves to the left and pushes the silver block 1701 close to the coarse grinding roller 13. The coarse grinding roller 13 grinds the silver block 1701 preliminarily. When the silver block 1701 moves to the left, the pressing component can also press the silver block 1701 to be Grind one end to ensure that the silver block 1701 moves stably to the left to prevent the silver block 1701 from shaking and tilting. The silver powder ground by the coarse grinding roller 13 falls downward and is filtered by the recovery component and then falls to the fine grinding roller 14. It is then finely ground by the fine grinding roller 14. The ground silver powder is gathered by the gathering bucket 15 and falls into the collection frame 16 to prevent the silver powder from scattering and falling and causing dust to fly. The unground metal particles filtered out by the recovery component will be transported to the coarse grinding roller 13 for re-grinding. When the push frame 17 pushes the silver block 1701 to grind to the final In the later stage, the elastic rope 110 no longer pulls the first top block 111, and the front and rear sides of the silver block 1701 cannot effectively support the first top block 111. At this time, the torsion spring 112 is reset to drive the front and rear first top blocks 111 to reverse, and the first top block 111 will contact the right side of the last corner of the silver block 1701, thereby pushing the scraps of the silver block 1701 to move to the left, applying sufficient pressure to the irregularly shaped small scraps of the silver block 1701, so that the scraps of the silver block 1701 can fit with the coarse grinding roller 13 for effective grinding.

[0034] When the device is used, the silver powder initially ground by the coarse grinding roller 13 falls downward to the screen 24, and the larger particles are filtered out by the screen 24. Since the screen 24 is inclined, the filtered metal particles are transported to the left into the guide frame 23, and then transported into the lower placement box 22 through the guide frame 23. The rotating frame 21 is then driven to rotate by the servo motor 2, and the rotation of the rotating frame 21 drives the placement box 22 to rotate. During the rotation of the rotating frame 21 and the placement box 22, the rotating frame 21 blocks the lower side of the guide frame 23 to prevent powder leakage from the lower side of the guide frame 23, and the placement box 22 is blocked by the closing plate 25.

The front and rear sides are fixedly connected with the second air cylinder 34, the piston end of the second air cylinder 34 is fixedly connected to the push frame 17, the piston rod 3501 is slidably connected in the first air cylinder 3, and the pressing frame 36 is slidably connected between the left and right piston rods 3501. The bottom end of the pressing frame 36 is provided with six rotatably connected rollers, which are used to press the silver block 1701 without affecting the movement and transportation of the silver block 1701. An elastic member 35 is connected between the pressing frame 36 and the piston rod 3501, and a connecting pipe 37 is connected between the upper side of the first air cylinder 3 and the rear of the adjacent second air cylinder 34.

[0036] When the device is used, the push frame 17 slides leftward, which pushes the piston end of the second air cylinder 34 to slide leftward, thereby squeezing the air in the second air cylinder 34 into the connecting pipe 37, and inputting the air into the first air cylinder 3 through the connecting pipe 37, thereby pushing the piston rod 3501 to slide downward. The downward sliding of the piston rod 3501 drives the pressing frame 36 to move downward to press the end to be ground, ensuring that the silver block 1701 moves stably to the left, and preventing the silver block 1701 from shaking and tilting and affecting the grinding. Under the action of the elastic member 35, the pressing frame 36 can The rod 3501 slides up and down, thereby buffering the excess downward stroke of the piston rod 3501, and under the action of the screw rod 32, the height of the mounting plate frame 31 can be adjusted, and then the overall height of the first air cylinder 3, the piston rod 3501 and the pressure frame 36 can be adjusted. When the grinding is completed, the electric slide rail 18 drives the push frame 17 to slide to the right, and the piston end of the second air cylinder 34 will also slide to the right, and then the air in the first air cylinder 3 is sucked out through the connecting pipe 37, so that the piston rod 3501 and the pressure frame 36 move upward and reset.

[0038] In the initial state, the magnet 41 is adsorbed on the right side of the frame 1. When the collection frame 16 is pushed into the frame 1, the limit block 4 will slide to the right on the collection frame 16, and then fold the folding film 42. When the staff needs to pull the collection frame 16 out of the frame 1, under the action of the magnet 41, the limit block 4 will slide to the left on the collection frame 16, and then unfold the folding film 42 to cover the upper side of the collection frame 16 to prevent silver powder from flying.
